White Mountain Hearth gives you realism combined with optimal heat in their 18 inch Sassafras Vent Free Log. The contour of each sassafras log along with the height of the stack makes this vent free log set from Empire complement the burner pattern for a lifelike fire. The popular Slope Glaze Burners raise the standard for dancing flames. Internal ceramic beads tumble the gas to create especially realistic flame movement. Your White Mountain Hearth Vent-Free log set creates a consistent, controlled heat – without hazardous flare-ups or chilling die-downs. These 18 inch vent free gas logs warm your room quickly and efficiently, while using about half the energy of a vented gas log. You can choose from a manual or remote controlled set. The remote choices are on/off with flame height adjustment or thermostatically controlled.
